Several error messages might be displayed at different times during the POST process for any single error condition. Address: A string of a5a6a5a5 was observed when a string of a5a5a5a5 was expected. For example: Power On Selftest Failed. Note — If only two DIMMs were installed and this set of errors occurred, the system would have beeped three times and powered off.

Warning messages do not contain a Repair Instructions line. Save all work in progress and close any open applications. As superuser in a terminal window of the system to run POST, type: init 0 You can view this output by connecting a serial terminal or a second system running a Tip connection through a terminal window. The second system must have a serial port capable of RS communications.

Use a crossover cable null-modem cable with the Tip connection. If your system does not have a DB-9 F connector at the serial port, adapters are available from most computer supply stores or from your Sun Microsystems sales representative. The following procedure configures for serial port 1, or TTY A. Ensure that the communication parameters are correct. Attach the crossover cable to the system being tested and then to the serial terminal or second system.

Start the Tip connection. Type: tip hardwire 3. Press the Return key several times to synchronize the h and shaking between the two systems. You should see the ok prompt. Type the post comm and. For example: ok post min max POST is run. This software enables the Sun Ultra 45 and Ultra 25 workstation to load an operating system. The operating system can be loaded from an installed hard drive, the DVD-dual drive, the network, or from some external boot device.

If an error occurs during that process, a message is usually displayed. You can use OpenBoot Diagnostics tools to help diagnose system problems. Type any key to stop. Check the Ethernet cable. Check the overall network status. The probe-ide utility displays the manufacturer and model of devices attached to the IDE buses. The tests help you narrow down a problem to a specific component.

An advantage of running OpenBoot Diagnostics through a Tip connection is that long output can be scrolled and saved. Set the auto-boot? Type: ok setenv auto-boot? Reset the system. Type: ok reset-all The system restarts and the ok prompt is displayed again. Set the diag-switch? Type: ok setenv diag-switch? Start OpenBoot Diagnostics. If the device has a self-test, the device function can be verified. Some cards may not support selftest. When the poll is finished, OpenBoot Diagnostics lists a menu of the tests that can be executed.

If a device node is not recognized, it is not listed in the menu. For example, if the Sun XVR graphics accelerator were removed from the system, the Sun XVR graphics accelerator test would not be available, and all remaining tests would shift location and be renumbered. Tests environmental controller. Checks headers and checksums. Tests the secondary or primary serial port at different baud rates.

For the simplest testing, follow this procedure. At the obdiag prompt, set the diagnostic passes to 1. Set the diagnostic level to maximum. Reseat the graphics accelerator in the PCI slot or replace it.

Problem with fan or other temperature controls. Check fan tray backplane connector. Problem with flash PROM on motherboard. Check the motherboard and replace if necessary. If no problem with the device, check the motherboard. Note — The help comm and provides additional information for configuring OpenBoot Diagnostics.

Using the previous examples, you would type: The following is a successful flashprom test. The following is an example of a serial loopback test with no connector. Searching for self-test methods. Rejecting alloc-mem! The battery has drained. Replace the battery. Attempt to run OpenBoot Diagnostics from a selected device node. Each DIMM in a pair is from a different manufacturer. Each DIMM in a pair has a different architecture.

The DIMMs are not used. OpenBoot Diagnostics failed to start. Some devices might be tied to other processes. Drive might be corrupted. Check internal connections. Check boot server. Install DIMMs in identical pairs. Check network connection. Sun VTS is a system exerciser that you can use to check for intermittent or long-term failures. Sun VTS software executes multiple diagnostic tests from a GUI that provides test configuration and status monitoring.

Use only Sun VTS 6. You can change power management settings in the Dtpower application or you can make changes by editing the power. The Dtpower application is easier to use. Editing the power. This chapter provides some basic power management instructions. There is also a mode for customizing the settings. St and ard All devices go into low-power mode. Customized Allows user to customize settings for displays and disks. Disabled No power management for any device.

Before you configure power management, consider the way that you use the Sun Ultra 45 or Ultra 25 workstation. If so, use only minimal power management, or none at all. The power. For more information see the power. The application exits and you are finished.

The window exp and s. Continue with the remaining steps. Set the Override Device Idle Time for displays or drives. Click OK to close the application. If any single device is powered up, the LED will stop flashing. To reactivate the Sun Ultra 45 or Ultra 25 workstation from low-power mode, press the spacebar on the keyboard or move the mouse. If you are connected remotely, any system activity that you initiate can bring the workstation out of low-power mode.

B-1 ,19 mm Other aspects of the Sun Ultra 25 are the same as the Sun Ultra 45 workstation. It is capable of sustained execution of four instructions per cycle, even with conditional branches and cache misses. Instructions are issued in program order to multiple functional units, and executed in parallel.

Instructions from two basic blocks are issued in the same group to further increase the number of instructions executed per cycle. Since each DIMM could be dual sided upper and lower banks , there are maximum of four data loads per physical bank.

The cache line is split across the two physical banks. Both banks are controlled by the memory controller. Note — DIMMs must always be installed in pairs. A memory controller sends requests in the pipeline, using 16 memory banks in the Sun Ultra 45 when fully loaded, and 8 memory banks in the Sun Ultra 25 when fully loaded.

When powering off, the Sun Ultra 45 or Ultra 25 workstation sends a Break signal out the serial ports. This break could interfere with a workstation-controlled server if the server is operating through a Tip connection. Note — You must reconfigure the alternate Break key sequence after a server power cycle. This action prevents any serial communication with the server. To re-establish serial communications, turn the key to the unlock position. Save the file. Reinitialize the kbd drivers.
